Description

Die Erfindung betrifft eine Aufhängevorrichtung für ein Sitz-oder Ruhemöbel mit relativ zueinander beweglichem Fuß und Lagerflächenteil, bei der das obere, ein Sitzen oder Liegen ermöglichende Lagerflächenteil durch Seilpendel an dem unteren Fußteil aufgehängt ist, wobei an jeder Aufhängungsstelle zwei oder mehrere Seilpendel funktionell in Reihe angeordnet sind, und die Lagerstellen der dem Lagerflächenteil und der dem Fußteil gegenüberliegenden Pendelenden miteinander verbunden sind.The invention relates to a suspension device for a piece of seating or rest furniture with a relatively movable foot and bearing surface part, in which the upper bearing surface part, which enables sitting or lying down, is suspended by rope pendulums on the lower foot part, with two or more rope pendulums functionally in series at each suspension point are arranged, and the bearing points of the bearing surface part and the pendulum ends opposite the foot part are connected to one another.

Eine Aufhängevorrichtung der genannten Art ist aus der internationalen Veröffentlichung WO-A-86/04793 bekannt. Bei dieser Vorrichtung besitzen die funktionell in Reihe geschalteten Seilpendel unterschiedliche Pendellängen und weisen damit jeweils unterschiedliche Eigenfrequenzen auf. Hierdurch soll bei Anregung des schwingungsfähigen Systems mit Impulsen wechselnder Frequenz stets eine Anregung zumindest eines dieser Seilpendel mit bzw. nahezu mit seiner Eigenfrequenz gewährleistet sein, um auch bei schwachen Impulsen ausreichende Schwingungsamplituden zu erhalten.A suspension device of the type mentioned is known from the international publication WO-A-86/04793. In this device, the functionally connected pendulums have different pendulum lengths and therefore each have different natural frequencies. In this way, when the system capable of oscillation is excited with pulses of varying frequency, an excitation of at least one of these rope pendulums with or almost at its natural frequency should always be ensured in order to obtain sufficient oscillation amplitudes even with weak pulses.

Der Erfindung liegt die Aufgabe zugrunde, eine Aufhängevorrichtung der genannten Art zu schaffen, die bei kompakter Bauweise ein Höchstmaß an Dynamisierung ermöglicht, d.h. ein Höchstmaß von Sensibilisierung gegenüber feinen Vibrationen bei gleichzeitigen guten Stabilisierungs- und Dämpfungseigenschaften bei großen Auslenkungen gewährleistet.The invention has for its object to provide a suspension device of the type mentioned, which allows for maximum dynamization with a compact design, i. A high degree of sensitization to fine vibrations with good stabilization and damping properties at large deflections is guaranteed.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei einer gattungsgemäßen Aufhängevorrichtung die in Reihe angeordneten Pendel etwa die gleiche Pendellänge aufweisen.This object is achieved in that the pendulums arranged in series have approximately the same pendulum length in a generic suspension device.

Zweckmäßigerweise besteht die Verbindung der Lagerstellen der dem Lagerflächenteil und der dem Fußteil gegenüberliegenden Pendelenden aus einem Rahmen, dessen Höhe der Pendellänge entspricht, wobei das am Lagerflächenteil befestigte Pendel an der Oberseite des Rahmens und das am Fußteil befestigte Pendel an der Unterseite des Rahmens befestigt ist. Bei einer bevorzugten Ausführungsform besteht der Rahmen aus zwei senkrecht übereinander angeordneten, mit Gummipuffern verbundenen Flacheisen. Das Lagerflächenteil ist mit einem Pendel verbunden, das durch eine Durchbrechung des unteren Flacheisens geführt ist und mit seinem anderen Ende am oberen Flacheisen befestigt ist. Das am Fußteil befestigte Pendel ist durch eine Durchbrechung im oberen Flacheisen mit seinem anderen Ende am unteren Flacheisen befestigt.Advantageously, the connection of the bearing points of the bearing surface part and the pendulum ends opposite the foot part consists of a frame, the height of which corresponds to the pendulum length, the pendulum fastened to the bearing surface part being fastened to the top of the frame and the pendulum fastened to the foot part being fastened to the underside of the frame. In a preferred embodiment, the frame consists of two flat irons arranged vertically one above the other and connected with rubber buffers. The bearing surface part is connected to a pendulum which is passed through an opening in the lower flat iron and is attached at its other end to the upper flat iron. The pendulum attached to the foot part is attached to the lower flat iron with its other end through an opening in the upper flat iron.

Eine vorteilhafte Ausgestaltung ist dadurch gekennzeichnet, daß eine Vielzahl von konzentrischen Rahmen vorgesehen ist, die durch die in Reihe angeordneten Seilpendel miteinander verbunden sind. Die Rahmen sind vorteilhafterweise übereinander fluchtend angeordnet. Zweckmäßigerweise weisen die Rahmen Durchbrechungen auf, durch welche die Pendel zur gegenüberliegenden Rahmenseite geführt sind. Gemäß einer vorteilhaften Ausgestaltung sind die Rahmen durch Federelemente, vorzugsweise durch nachgiebige Gummipuffer, miteinander verbunden. Die Rahmen können je nach Anwendungsgebiet dreieckig, viereckig oder auch mehreckig ausgestaltet sein, wobei die Pendelverbindungen vorzugsweise im Bereich der Ecken vorgesehen sind. Die Rahmen können vorteilhafterweise kastenartig mit geschlossenen Seitenwänden ausgebildet sein.An advantageous embodiment is characterized in that a plurality of concentric frames are provided which are connected to one another by the rope pendulums arranged in series. The frames are advantageously aligned one above the other. The frames expediently have openings through which the pendulums are guided to the opposite side of the frame. According to an advantageous embodiment, the frames are connected to one another by spring elements, preferably by flexible rubber buffers. Depending on the field of application, the frames can be triangular, quadrangular or even polygonal, the pendulum connections preferably being provided in the area of the corners. The frames can advantageously be box-shaped with closed side walls.

Eine bevorzugte Ausgestaltung ist dadurch gekennzeichnet, daß eine Vielzahl von gleich ausgebildeten Rahmen, jedoch unterschiedlichen Querschnitts vorgesehen sind, und daß bei benachbarten Rahmen der größere Rahmen Stege aufweist, an denen das eine Ende eines Pendels befestigt ist, welches mit seinem anderen Ende am nächst kleineren Rahmen festgelegt ist. Vorzugsweise greift das am Lagerflächenteil befestigte Pendel am größten Rahmen an, während das am Fußteil befestigte Pendel mit dem kleinsten Rahmen verbunden ist.A preferred embodiment is characterized in that a plurality of frames of the same design but different cross-sections are provided, and that in the case of adjacent frames the larger frame has webs to which one end of a pendulum is fastened, which is connected to its other end is set to the next smaller frame. Preferably, the pendulum attached to the bearing surface part engages the largest frame, while the pendulum attached to the foot part is connected to the smallest frame.

In besonderen Ausführungsformen sind zwischen den relativ zueinander beweglichen Teilen Anschlagelemente, vorzugsweise gelagerte Kugeln angeordnet, um deren Auslenkung zu begrenzen.In special embodiments, stop elements, preferably ball bearings, are arranged between the parts which are movable relative to one another in order to limit their deflection.

Eine vorteilhafte Ausgestaltung ist dadurch gekennzeichnet, daß die Rahmenteile mit den sie verbindenden Pendeln in einem am Fußteil oder Lagerflächenteil befestigten Gehäuse untergebracht sind und daß das Fußteil das Gehäuse mittig durchläuft, wobei zwischen dem Fußteil und dem Gehäuse ein Abstand vorgesehen ist, der Schwingungen zwischen dem Lagerflächenteil mit Gehäuse einerseits und dem Fußteil andererseits erlaubt.An advantageous embodiment is characterized in that the frame parts with the pendulums connecting them are accommodated in a housing fastened to the foot part or bearing surface part and that the foot part runs through the housing in the center, a distance being provided between the foot part and the housing, the vibrations between the Bearing surface part with housing on the one hand and the foot part on the other allowed.

Das in Fig. 1 dargestellte Sitzmöbel 10 besteht aus einem oberen Lagerflächenteil 12, das mittels eines von ihm ausgehenden, sich nach unten erstreckenden Trageelementes 14 über Seilpendel 16 pendelnd an einem unteren Fußteil 18 aufgehängt ist. Das Trageelement 14 kann entweder rahmen- oder kastenförmig ausgebildet sein oder aber aus mehreren Tragearmen bestehen. An jeder Aufhängungsstelle sind zwei Seilpendel 16, die etwa die gleiche Pendellänge aufweisen, funktionell in Reihe geschaltet. Die Lagerstellen der dem Lagerflächenteil 12 und der dem Fußteil 18 gegenüberliegenden Pendelenden sind über einen Rahmen 20, dessen Höhe der Pendellänge entspricht, starr miteinander verbunden. Das am Lagerflächenteil 12 befestigte Seilpendel 16 ist pendelnd an der Oberseite des Rahmens 20 aufgehängt, während das am Fußteil 18 befestigte Seilpendel 16 an der Unterseite des Rahmens 20 befestigt ist. Die Pendel 16 sind hierbei über Durchbrechungen in dem Rahmen 20 zu der jeweils gegenüberliegenden Rahmenseite geführt.The seating furniture 10 shown in FIG. 1 consists of an upper bearing surface part 12 which is suspended on a lower foot part 18 by means of a supporting element 14 extending from it and extending downwards via pendulum 16. The support element 14 can either be frame-shaped or box-shaped or can consist of several support arms. At each suspension point, two rope pendulums 16, which have approximately the same pendulum length, are functionally connected in series. The bearing points of the bearing surface part 12 and the pendulum ends opposite the foot part 18 are rigidly connected to one another via a frame 20, the height of which corresponds to the pendulum length. The rope pendulum 16 attached to the bearing surface part 12 is suspended from the top of the frame 20 while the rope pendulum 16 attached to the foot part 18 is attached to the underside of the frame 20. The pendulums 16 are guided through openings in the frame 20 to the opposite side of the frame.

Als Schutz können die Rahmenteile mit der sie verbindenden Pendeln 16 in einem am Fußteil 18 oder Lagerflächenteil 12 befestigten Gehäuse untergebracht sein. Das Fußteil 18 durchläuft hierbei das Gehäuse mittig, wobei zwischen dem Fußteil 18 un dem Gehäuse ein Abstand vorgesehen ist, der Schwingungen zwischen dem Lagerflächenteil 12 mit Gehäuse einerseits und dem Fußteil 18 andererseits erlaubt.As protection, the frame parts with the pendulums 16 connecting them can be accommodated in a housing fastened to the foot part 18 or bearing surface part 12. The foot part 18 runs through the housing in the middle, a distance being provided between the foot part 18 and the housing, which allows vibrations between the bearing surface part 12 with the housing on the one hand and the foot part 18 on the other hand.

Die dargestellte Aufhängevorrichtung ist im Vergleich zu Aufhängevorrichtungen herkömmlicher Art durch ein wesentlich verbessertes Schwingungsverhalten bei kompakter Bauweise gekennzeichnet. Sie ermöglich auch bei feinsten Vibrationen ein Höchstmaß an Dynamisierung bei gleichzeitigen guten Stabilisierungs- und Dämpfungseigenschaften großen Auslenkungen gegenüber.The suspension device shown is compared to suspension devices of a conventional type due to a significantly improved vibration behavior with a compact design featured. It enables a high degree of dynamization even with the finest vibrations, while at the same time having good stabilization and damping properties against large deflections.

Eine zusätzliche Verbesserung des Schwingungsverhaltens läßt sich dadurch erreichen, daß eine Vielzahl von konzentrischen Rahmen 20 vorgesehen ist, die durch in Reihe geschalteten Seilpendel 16 miteinander verbunden ist. Eine entsprechend ausgebildete, erfindungsgemäße Aufhängevorrichtung ist in Fig. 2 beispielhaft für ein Sitzmöbel 10 schematisch dargestellt. Die Verbindung zwischen dem Trageelement 14 des Lagerflächenteils 12 und dem Fußteil 18 erfolgt über drei Rahmen 20 unterschiedlichen Querschnittes, die konzentrisch ineinander angeordnet sind. Bei benachbarten Rahmen 20 weist jeweils der kleinere Rahmen 20 Stege 22 auf, an denen das eine Ende eines Seilpendels 16 befestigt ist. Diese Stege 22 sind so über den jeweils nächstgrößeren Rahmen 20 geführt, daß das Seilpendel 16 mit seinem anderen Ende an der Unterseite des nächstgrößeren Rahmens 20 festgelegt ist. Das am Lagerflächenteil 12 befestigte Pendel 16 greift hierbei an der Oberseite des größten Rahmens 20 an, welcher nicht mit einem entsprechenden Steg 22 versehen ist. Das am Fußteil 18 befestigte Pendel 16 ist mit dem kleinsten Rahmen 20 verbunden. Die Pendel 16 sind hierbei über Durchbrechnungen in den Rahmen 20 zu den jeweiligen Aufhängepunkten geführt. Eine Draufsicht auf diese erfindungsgemäße Rahmenanordnung ist zur Verdeutlichung in Fig. 3 dargestellt.An additional improvement in the vibration behavior can be achieved in that a plurality of concentric frames 20 is provided, which are connected to one another by series-connected rope pendulums 16. A correspondingly designed suspension device according to the invention is shown schematically in FIG. 2 for an example of seating furniture 10. The connection between the support element 14 of the bearing surface part 12 and the foot part 18 takes place via three frames 20 of different cross-section, which are arranged concentrically one inside the other. In the case of adjacent frames 20, the smaller frame 20 has webs 22, to which one end of a cable pendulum 16 is attached. These webs 22 are guided over the next larger frame 20 in such a way that the cable pendulum 16 is fixed at its other end to the underside of the next larger frame 20. The pendulum 16 attached to the bearing surface part 12 engages the top of the largest frame 20, which is not provided with a corresponding web 22. The pendulum 16 attached to the foot part 18 is connected to the smallest frame 20. The pendulums 16 are guided through openings in the frame 20 to the respective suspension points. A top view of this frame arrangement according to the invention is shown in FIG. 3 for clarification.

Bei dem in Fig. 4 dargestellten Ausführungsbeispiel besteht der Rahmen 20 aus zwei senkrecht übereinander angeordneten Flacheisen 20a, 20b, die über Gummipuffer 24 miteinander verbunden sind. Das an dem Lagerflächenteil 12 befestigte Seilpendel 16 ist durch eine Durchbrechung des unteren Flacheisens 20a geführt und mit seinem oberen Ende am oberen Flacheisen 20b pendelnd aufgehängt. Das am Fußteil 18 befestigte Pendel 16 ist durch eine Durchbrechung im oberen Flacheisen 20a mit seinem anderen Ende am unteren Flacheisen befestigt. Zwischen den relativ zueinander beweglichen Teilen sind Anschlagelemente 26 angeordnet, um deren Relativbewegung zu begrenzen. Die zwischen dem oberen Flacheisen 20b und dem Fußteil 18 sowie dem unteren Flacheisen 20a und dem Lagerflächenteil 12 angeordneten Anschlagelemente 26 bestehen aus gelagerten Kugeln, um auch eine seitliche Bewegung zu ermöglichen.In the exemplary embodiment shown in FIG. 4, the frame 20 consists of two flat irons 20a, 20b arranged vertically one above the other, which are connected to one another via rubber buffers 24. The cable pendulum 16 fastened to the bearing surface part 12 is guided through an opening in the lower flat iron 20a and suspended with its upper end on the upper flat iron 20b. At the foot part 18 attached pendulum 16 is fixed by an opening in the upper flat iron 20a with its other end on the lower flat iron. Stop elements 26 are arranged between the parts movable relative to one another in order to limit their relative movement. The stop elements 26 arranged between the upper flat iron 20b and the foot part 18 as well as the lower flat iron 20a and the bearing surface part 12 consist of supported balls in order to also enable lateral movement.

Im Unterschied zu den bisher gezeigten Ausführungsbeispielen, bei denen die Rückenlehne 28 des Sitzmöbels 10 einstückig mit dem Lagerflächenteil 12 verbunden war, ist die Rückenlehne 28 in dem gezeigten Ausführungsbeispiel über ein Federelement 30 mit dem aus einem Flacheisen bestehenden unteren Trageelement 20a des Rahmens 20 verbunden. Im Vergleich zu herkömmlichen Sitzmöbeln wird hierdurch ein von den Schwingungen des Lagerflächenteils 12 im wesentlichen entkoppeltes Schwingen der Rückenlehne 28 ermöglicht. Hierdurch läßt sich eine zusätzliche Verbesserung des Schwingungsverhaltens des Sitzmöbels erzielen. Die erfindungsgemäße Verbindung der Rückenlehne 28 über ein Federelement 30 mit unteren Tragelement 20a des Rahmens 20 ist zur Verdeutlichung in Fig. 5 in Draufsicht schematisch dargestellt.In contrast to the previously shown exemplary embodiments, in which the backrest 28 of the seating furniture 10 was connected in one piece to the bearing surface part 12, the backrest 28 in the exemplary embodiment shown is connected via a spring element 30 to the lower support element 20a of the frame 20, which is made of a flat iron. In comparison to conventional seating furniture, this enables the backrest 28 to oscillate essentially decoupled from the vibrations of the bearing surface part 12. This allows an additional improvement in the vibration behavior of the seating furniture to be achieved. The connection of the backrest 28 according to the invention via a spring element 30 to the lower support element 20a of the frame 20 is shown schematically in FIG. 5 in a top view.

Die Wirkungsweise der erfindungsgemäßen Aufhängevorrichtung wurde in den vorstehenden Beispielen anhand eines Sitzmöbels beispielhaft dargestellt. Sie kann vorteilhafterweise jedoch z.B. auch bei der Lagerung hochempfindlicher Maschinen oder Geräte Anwendung finden.The operation of the suspension device according to the invention was exemplified in the above examples using a piece of seating. However, it can advantageously e.g. can also be used to store highly sensitive machines or equipment.
